Fuel Efficiency and the Yaris

[romeroalfred]

Hey there guys and gals just wanted to ask if any of ya'll place the automatic yaris on neutral when ya come to stops to allow the car to coast. I usually only drive in the city og Chicago and I wager I average 28 maybe 29 mpg. I would like to hear what ya think?

Coasting in neutral to a stop is not as efficient as simply letting the engine brake the car. See the sticky on DFCO. Simply put, the computer cuts fuel flow entirely down to about 1100 rpms, using no fuel at all. Coasting in neutral puts the car in idle and continues to consume fuel.

I usually use this feature and take it one step further by watching the tach and when it approaches 1100 rpm I click the transmission out of D and into 3 to keep the rpm's in the range where fuel is not burned. Then, when at the light, I pop it up into neutral so as to idle without a load on the engine. I use this same technique when making a right turn when I have a green light or traffic is clear for a rolling stop - just remember to pop the tranny from 3 back up into D otherwise you'll wind up revving too high when you get back up to speed. The gated shifter makes these maneuvers particularly easy IMO. When I first bought my car, the gated shifter seemed like a silly Euro gimmick, but I'm absolutely sold on it now!
